rc.xml contains inconsistent whitespace characters

[Removed by request]

I'm using Ubuntu 13.10 dev with lxde-common 0.5.0-4ubuntu4. The file /usr/share/lxde/openbox/rc.xml contains on the most places a space for indenting but on a few lines it is mixing up spaces with \xc2\xa0 (NO-BREAK SPACE). I think this should be more consistent and all occurrences of \xc2\xa0 should be replaced with a space. Here is the output:

sworddragon@ubuntu:~/data/data$ ack-grep '\xc2\xa0'
